-   american fuzzy lop - GCC wrapper for GCC plugin
-   ------------------------------------------------

-   Written by Austin Seipp <aseipp@pobox.com> and
-              Laszlo Szekeres <lszekeres@google.com> and
-              Michal Zalewski <lcamtuf@google.com>
-
-   GCC integration design is based on the LLVM design, which comes
-   from Laszlo Szekeres.

-   This program is a drop-in replacement for gcc, similar in most
-   respects to ../afl-gcc, but with compiler instrumentation through a
-   plugin. It tries to figure out compilation mode, adds a bunch of
-   flags, and then calls the real compiler.

-     1) We need to convince the compiler not to optimize out the signature.

-
-     2) We need to convince the linker, when called with -Wl,--gc-sections,
-        not to do the same. This is done by forcing an assignment to a
-        'volatile' pointer.
-
-     3) We need to declare __afl_persistent_loop() in the global namespace,
-        but doing this within a method in a class is hard - :: and extern "C"
-        are forbidden and __attribute__((alias(...))) doesn't work. Hence the
